The so-called Divine Sarcophagus was not actually a coffin but a black box that was one meter in length and less than half a meter in height. The box was made of an unknown material and its surface was engraved with dark red ancient runes. Several straight nicks divided the top half of the box into several large and small polygons, making it look like it was made up of many pieces.
It was smaller than Hao Ren had expected.
